The two DNA strands are held together by interchain hydrogen bonds. H-bonds pair the bases in one chain to the complementary bases in the other chain. (A/T and G/C).
1 the gene coding for the protein required untwists then unzips, the H-bonds between the strands break. 2  free RNA nucleotides form complementary base pairs [base pair: The pair of nitrogenous bases that connects the complementary strands of DNA.] with one strand of DNA bases. 3  weak hydrogen bonds form between base pairs.
